Somehow, rapper Lil Mama ended up on stage with Jay-Z and Alicia Keys during their performance of Hov's "Empire State of Mind" – and the hip-hop mogul, whose "The Blueprint 3" is the top-selling album in the country for a second week running – doesn't approve.

"To interrupt that moment for us, I don't think that was the right thing to do," Jay said on Angie Martinez's Hot 97 radio show in New York City on Wednesday. "It was a lot of planning that went into that performance. To disrupt that was outta line."
